鱼钩轮18584073127 ______[答案] (一)伏安法测电阻 伏安法测电阻是初中物理中一个重要的实验,本实验可以利用电压表和电流表分别测出未知电阻Rx的电压、电流,再用欧姆定律的变形公式求出Rx的阻值.由于电压表也叫伏特表,电流表也叫安培表,所以这种用电压表、电流...

令欣沸942伏安法测电阻中的分流、分压作用是只什么意思? -
鱼钩轮18584073127 ______[答案] 伏安法测电阻通常用的是串联电路,不存在分流的问题,因为串联电路电流处处相等,分压是指串联分压,和各部分电阻成正比(可用欧姆定律加以证明),在此实验中承担分压作用的滑动变阻器,它起到保护电路和改变被测电阻两端的电压和电流...

令欣沸942为什么初中伏安法测电阻是串联 而高中采用分压法就是并联?? -
鱼钩轮18584073127 ______ 在高中,很多学过的知识会被推翻. 高中用伏安法测电阻,是因为要画伏安特性曲线, 该曲线要求测量值从零开始,分压法可以实现, 而限流电路(串联)的测量值不能从零开始.
